A little over a year ago, developer Doug Melton delighted us with Android emulators for three popular TI calculators - TI-83, TI-85, and TI-86. Nostalgic and surprisingly useful, they resonated with many of you, but, unfortunately, TI forced Doug to take them all down a short while after.

You see, Doug actually shipped them with the original ROMs included, which was great for one-click installations, but apparently not so great for intellectual property.
